We have been living in ours since June 2022, purchased used. This has been an exceptional unit. Our 2022 Ram 3500 pulls this without issue. Lots of storage, I can't say enough great things about our home!

WOW not even a week old never was able to use it. I believe Grand Design is now making very expensive garbage.Run away do not purchase one of these Trailers. Buyer beware. You have been warned. All I have now is a 120k lump of coal and a payment.

Purchased new in 2016 (September) from at the time the only dealer in Ontario. PDI was poorly done which as it turns out was only the beginning of the poor quality and engineering of this unit. We do really like the layout and livability of this unit and have used it extensively in Ontario as well as in the USA. Normal highway,interstate and campground driving. Since new we have replaced taps, all tires (China Bombs),light fixture in kitchen, equalizers twice, all leaf springs, rear ladder separated from trailer ( I weigh 185 lbs), front passenger side slide motor ,water damage in rear outdoor kitchen ( floor destroyed ). Door for fridge access outside was improperly installed . Now we have structural failure in front drivers side and delaminating wall that needs to be repaired this winter. Main brain for auto level system failed. All in nearly $30000 in bills when all in. Grand Design basically says so said sucks to be you. We have traded it in for a 2 year newer other brand and will never deal with this company again. Amazing marketers, lousy builder !!!

We have so enjoyed our Momentum. The Artic package proved its worth during snow-maggeddon. My husband and I purchased our RV April of 2020 brand new from McClains RV in Denton, TX. It has been our main living space when we are not working.
Our Children has visited and the quietness of the garage living space with the 2nd bathroom provided an enjoyable stay for all.
With many amenities from the Artic package with the amazing Onan that kept us warm and with power when the power was out in Texas, to the auxiliary fuel tank and water tanks and the easily convertible garage space, we give this RV a 10 out 10 on ease to care, move and haul.

We thoroughly enjoyed this rv. We used the garage space for an office and Art Studio. Painting and framing supplies all on board as we traveled. The dogs loved the back deck. Ability to see out and watch passers by. The floorplan has a dinette - a place to sit down with a plate. The sectional seating / heated recliners were wonderful for watching tv. The kitchen was a joy! plenty of space to make gourmet meals - pantry storage, pan storage - it really had it all. The Furion appliances were great. Golf clubs, art gear, dog crate............. all the room you could ask for. The bathroom shower had a seat and shelves for your stuff. Under the bed storage. I highly recommend the floorplan and the Grand Design builders.

This is our first Grand Design and we definitely love the quality.
